Shout out to UNSTABLE_HERO for sending me the f6a, greatly appreciated, thanks

i hope the new bios doesn't 'nick' your board

i have problems with my 1.3rev i have a q9450 and with my first x48t 1.1rev it was running at 3680 at 1.300v and now only 3300!i tried everything and i cant go over 3300:

i tried on f5a-f5-f6a but i cant go over 3300!the strange thing is that if i set mch volt at +0.20 and above the board hungs and resets to default! my cpu temps are 34 idle and 56 at full load!and system temp near to 48c!with loadline enable i have 0.03 vdroop!and if i set the volts at 1.2750 the pc health shows 1.264 and 1.284 every second it changes from 1.264 to 1.284...... but not 1.275!strange things!my 1.1 rev was stable!any help or suggestions?

Is your memory on the way out ?? try each stick seperately at your original stable settings & see if it's more stable.
What exactly were your original stable settings ?? For example os 3.33D your current setting , or your original stable setting ??

but i cant go higher with higher volts and more relaxed latencies!i also stuck when i give +0.20 or higher at mch volts!so bye-bye 1.1rev and 3680mhz welcome 1.3 with 3300!the f5 killer bios ghost is back...i would have my 1.1 rev if the first f5 was good and not the damned 1.3rev that they gave me!

so you saw no leap in stability
What happens if you drop your divider down from 4.00D to 3.33D ?? are you able to lft voltages then ??
It just takes your memory out of the front line & hopefully give us an idea what else may be a problem. I don't think it's the board revision that's causing this.

SUPERSHANKS !!!!!

you have got to get you one of these Hannspree model HF289H 28 inch monitors wow!!

it was a new monitor or a 4870 x2 its just well wow 1920 x 1200 games are life like...

500.00 USD whats that 300 pounds but it worth ever bit..

hey UNSTABLE_HERO why is this in normal: (G)MCH OverVoltage Control: Normal

if you don't add voltage, you are not going anywhere with your overclock...man, you need at least +0.20v or more!

sonds great , but I'll have to factor in the £ of a new , bigger coffee table , current one would be dwarfed by that

the board cant start sometimes with +0.20 or +0.30 is so unstable with high voltages!at 3300 runs fine with normal or +0.10 or +0.15!my 1.1 rev could run at 3400 stable with mch at normal!only for 3600 was needed +0.20!the only thing that changed is the board from 1.1rev to 1.3rev. after the retailer guaranty cause of the bad f5!i tried 3.33D and lower deviders!i dont think that it is the ram!my ram is 1600 7-7-7-18 at 1.90v so i tried 1452 at 8-7-7-21 at 1.95volt!i think maybe a bad board or something does not fit?or the north bridge is overheating and is unstable when i give +0.20 and more!it seems that theres a strange big wall at 3300!i give more cpu volts more mch more fsb something stucks me!also i see a bigger vdroop 0.03-0.04 i used to have 0.02 the good old times
stable FSB 413 3.3 ][unstable FSB 419 3.35
cpu=1.2675 ......... ][cpu 1.3000
mch= normal ........ ][mch +0.15 OR +0.20(some times does not start)
fsb=+0.10V .......... ][fsb +0.20
WITH RAMS AND SUBTIMMINGS VERY RELAXED!
